Define solvent
Able to dissolve other substances
Define solute
The minor component ( smaller amount ) in a solution dissolved in the solvent.
Define solubility
Referring to the ability for a given substance, the solute, to dissolve in a solute
Name 3 things that can increase the rate of solubility
Increase temperature
Smaller particles ( crushed tablet compared to whole tablet )
Stirring the solution
If you have 80 milliliters of vinegar and you add 20 milliliters of water. In this solution, the water is identified as what part of the solution
The water would be the solute because it is the smaller amount
Is the process of dissolving a solute in a solvent a chemical reaction or physical reaction? Explain why.
Physical change because the parts never chemical combine
Why is water described as the universal solvent?
The unequal sharing of electron between oxygen and hydrogen
Explain what happens to solubility when you increase the temperature.
As you increase temperature the solubility increase.
Why is water described as a polar substance?
A positive end and a negative end positive charge
What most impact whether a substance will dissolve in water?
Polarity ( if it is polar it will dissolve, if non polar will not dissolve)
What is a pH level?
Is a measure of how acidic or basic a substance is.
Characteristics of an acid
Taste sour react
strongly with metals
Oh level 0-6
Combining acids and base what happens
They neutralize each other
What’s a neutral pH
7
A liquid with a ph of 3.0 is how many time more acidic than one with a ph of 4.0
Ten times
